[libvirt] [PATCH] esx: Avoid Coverity warning about resource leak in esxOpen
by Matthias Bolte 02 Feb '13

02 Feb '13

Commit 4445e16bfa8056980ac643fabf17186f9e685925 changed the signature of esxConnectToHost and esxConnectToVCenter by replacing the esxPrivate pointer with virConnectPtr. The esxPrivate pointer was then retrieved again from virConnectPtr's privateData. This resulted in a NULL pointer dereference, because the privateData pointer was not yet initialized at the point where esxConnectToHost and esxConnectToVCenter are called. This was fixed in commit b126715a48cd0cbe32ec6468c267cd8cf2961c55 that moved the initialization of privateData before the problematic calls. Coverity tagged the esxPrivate pointer a potentially leaked because of the conditional free call. But this is a false positive, there is not actual leak. Avoid this warning from Coverity by making the call to esxFreePrivate unconditional and changing esxConnectToHost and esxConnectToVCenter back to take a esxPrivate pointer directly. This allows to assign esxPrivate to the virConnectPtr's privateData pointer as one of the last steps in esxOpen making it more obvious that it is not initialized during the earlier steps of esxOpen. --- This patch is meant as a replacement this patch: https://www.redhat.com/archives/libvir-list/2013-January/msg00530.html src/esx/esx_driver.c | 23 ++++++++++------------- 1 file changed, 10 insertions(+), 13 deletions(-) diff --git a/src/esx/esx_driver.c b/src/esx/esx_driver.c index 1366c81..dad10a1 100644 --- a/src/esx/esx_driver.c +++ b/src/esx/esx_driver.c @@ -650,7 +650,8 @@ esxCapsInit(esxPrivate *priv) static int -esxConnectToHost(virConnectPtr conn, +esxConnectToHost(esxPrivate *priv, + virConnectPtr conn, virConnectAuthPtr auth, char **vCenterIpAddress) { @@ -663,7 +664,6 @@ esxConnectToHost(virConnectPtr conn, esxVI_String *propertyNameList = NULL; esxVI_ObjectContent *hostSystem = NULL; esxVI_Boolean inMaintenanceMode = esxVI_Boolean_Undefined; - esxPrivate *priv = conn->privateData; esxVI_ProductVersion expectedProductVersion = STRCASEEQ(conn->uri->scheme, "esx") ? esxVI_ProductVersion_ESX : esxVI_ProductVersion_GSX; @@ -785,7 +785,8 @@ esxConnectToHost(virConnectPtr conn, static int -esxConnectToVCenter(virConnectPtr conn, +esxConnectToVCenter(esxPrivate *priv, + virConnectPtr conn, virConnectAuthPtr auth, const char *hostname, const char *hostSystemIpAddress) @@ -796,7 +797,6 @@ esxConnectToVCenter(virConnectPtr conn, char *unescapedPassword = NULL; char *password = NULL; char *url = NULL; - esxPrivate *priv = conn->privateData; if (hostSystemIpAddress == NULL && (priv->parsedUri->path == NULL || STREQ(priv->parsedUri->path, "/"))) { @@ -1008,8 +1008,6 @@ esxOpen(virConnectPtr conn, virConnectAuthPtr auth, priv->supportsLongMode = esxVI_Boolean_Undefined; priv->usedCpuTimeCounterId = -1; - conn->privateData = priv; - /* * Set the port dependent on the transport protocol if no port is * specified.

[libvirt] [Sheepdog][Libvirt]Test boot VMs from sheepdog volumes in Libvirt
by harryxiyou 02 Feb '13

02 Feb '13

Hi all, We can get "Boot VMs from sheepdog volumes in Libvirt" way from https://github.com/collie/sheepdog/wiki/Libvirt like following. a, prepare a file containing an XML domain description $ cat > sheepdog.xml <domain type='qemu'> <name>testvm</name> <memory>1048576</memory> <os> <type arch='x86_64'>hvm</type> </os> <devices> <disk type='network'> <source protocol="sheepdog" name="testvdi"/> <target dev='hda' bus='ide'/> </disk> <graphics type='vnc' port='-1' autoport='yes'/> </devices> </domain> b, boot from testvdi with virsh $ virsh create sheepdog.xml c, connect to a VNC console of the running VM $ vncviewer localhost I have some following questions about up three steps. 1, Before a or b(up boot step) step, should we have to install our OS into 'testvdi'? That is to say, we have to install OS from os.iso file into 'testvdi', which should use 'qemu-system-x86_64' command to install OS, right? 2, Before this test, shoul we have to build Sheepdog, QEMU, Libvirt environment? 3, This is the storage online management in Libvirt, right? 4, This test just test the codes Morita take a patch named "add network disk support" for Libvirt, which is located here: http://libvirt.org/git/?p=libvirt.git;a=commit;h=036ad5052b43fe9f0d197e89fd… and also test Sheepdog driver for QEMU, right? 5, If i installed a 32bits OS to testvdi, should i modify <os> <type arch='x86_64'>hvm</type> </os> to be <os> <type arch='x86'>hvm</type> </os> , right? 6, The step c (up boot step), which is $ vncviewer localhost Actually, i am not clear about this 'localhost'. Why should we link localhost but other ip addresses? Could anyone please give me some suggestions? Thanks in advance ;-) -- Thanks Harry Wei

[libvirt] [PATCH 0/7] documentation improvements - again
by Claudio Bley 01 Feb '13

01 Feb '13

Hi. The first two patches are aimed at avoiding generation of empty argument description lists, which might happen if a function has no documentation for some argument or its return type. This was happening with virTypedParams* functions (see https://www.redhat.com/archives/libvir-list/2013-January/msg01428.html) Patch #3 is just a small cleanup, since a table is not the right thing to use and it looks better in some circumstances. Patch #4 sports processing of code blocks embedded into comments. Basically, it is similar to markdown syntax, except that you only need to indent your code with 2 spaces. Patch #5 prepares for the later patches being able to distinguish between different <pre> blocks. Patch #6 and #7 are pretty much self explanatory, I guess. Note, that SHJS's license is GPLv3. Claudio Bley (7): docs: don't write out empty info attributes for function arguments docs: only generate function argument info for args with a description docs: use a div instead of a 3 column table for undisclosed notices docs: process code blocks similar to markdown docs: add class "description" to div's containing descriptions docs: define style of code blocks inside descriptions docs: syntax highlight code blocks using SHJS docs/apibuild.py | 8 +- docs/libvirt.css | 8 ++ docs/newapi.xsl | 209 +++++++++++++++++++++++++++++-------------------- docs/page.xsl | 5 +- docs/sh_c.min.js | 1 + docs/sh_emacs.min.css | 1 + docs/sh_main.min.js | 4 + 7 files changed, 148 insertions(+), 88 deletions(-) create mode 100644 docs/sh_c.min.js create mode 100644 docs/sh_emacs.min.css create mode 100644 docs/sh_main.min.js -- 1.7.9.5

[libvirt] Canonical citation for Libvirt
by Lempereur, Brett 01 Feb '13

01 Feb '13

Hi, Is there a canonical paper I can cite for Libvirt in academic publications? The best I've found so far is Bolt, M., Birkenheuer, G., Niehörster, O., & Brinkmann, A. (2010). Non-Intrusive Virtualization Management using Libvirt. Proceedings of the 2nd Design, Automation, and Test in Europe Conference (DATE'10) (pp. 1-6). Dresden, Germany: IEEE. Retrieved from http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=5457142&isnumber=54… A lot of frameworks used in academic work have sort of "standard" citations, people that use the framework tend to cite that paper. The authors get citations, we get cool frameworks, everyone wins.
